AM ROS 3-1131), or NEWPORT,"xnn'rucxy- METHOD OF POLISHING METAL "SURFACES.

No Drawing all whom it may concern: L Be it known that I, AMBRosE Rim). a citiport, in the county of Campbell and State of Kentucky, have invented a new and useful Method of Polishing Metal Surfaces, of

which-the following is a specification.

This invention has reference to improvements in polishes for metal surfaces andin the method of applying such polishes, and

being resistant both to wear and heat.

The polish is applicable to various metal surfaces, especially sheet metal surfaces and to stoves and furnaces and also to stove pipes where the polish is subjectedto the action of heat while the polish is'highly.

resistant to ordinary wear.

The improved polish is composed of boiled linseed oil, five parts, varnish one part, and

; pulverized graphite in sufiicient quantity to H make a compound of'the consistency of thick paste.

It will be understood however that the proportion given in the .aboveexample need not be strictly adhered to but .may be somewhat varied without material harm to theresult obtained. The varnish employed should be a varnish of good grade. A copal varnish will answer.

In preparing the polish the oil is first brought to,:the boiling point and then the varnish is added while the oil is being stirred, and the stirring is continued until the ingredients are thoroughly mixed. Then Whlle the mixture is still at the boiling point pulverized graphite is added until the 'compound is of a consistency about that of thick paint, the stirring being continued rubbed carefully and uniformly. Then another cloth is slightly charged with raw linseed oil, or with other oils, though linseed Specification of Letters Patent. Application filed February 9,121 10. SerialNo. 542,912.

oil is the best, and with this cloth all surplus of the application-to the surface to be treated is removed and the wiping is continued until there is left a smooth but slightly sticky s11"- face. 'Now with a soft dry cloth dipp lnto dry pulverized graphite, graphite is ap plied to the sticky surface until it has been, covered.uniformly, after which the surface may be rubbed to a high polish with little effort.

' After the application of the powder and Patented Ap1a4, 1911.

the polishing of thesame the article is baked at atemperature of fronrtliree hundred degrees to six hundred degrees Fahrenheit. This serves to make the coating-hard and durable.

If it be desirable to obtain a greater luster,

a second coating may be applied after the first coating has been baked.

.KVhat-is claimed is 1. The method of polishing metal surfaces, which consists in first producing an adhesive oily layer containing graphite upon the surface, then applying dry graphite I thereto, and then polishing the graphite. f 2. The method of coating metal surfaces which consists in first producing a thin adhesivedrying oily layer upon the surface, then removing the greater part of the layer by a suitable solvent, then applying dry graphite to the oily layer, then polishing the graphite, and finally baking the coating.

3. The method ofcoating metal surfaces,

which consists in first producing an adhesive drying oily layer containing graphite uponthe surface, then applying dry graphite thereto. then polishing the graphite, and finally baking the coating.

, 4. The method of coating metal surfaces which consists in first produclng a drying oily layer containing graphite upon the surface, then-removing the. surplus, then applying dry graphite to theoily layer, then polisliing the graphite, and finally baking the coating. I

5. The method of coating metal surfaces, which consists in' first producing upon the surface a layer containing boiled linseed. oil, varnish and graphite, illOH- removing the surplus from the surface. then applying graphite thereto, then polishing the graph ite, .and finally baking the coating.

6. The method of polishing metal surfaces which consists in producing upon the surface to be polished a sticky oily layer containing graphite,' then applying powdered graphlte, and then pollshing the graphite;

7. The method of producing upon metal surfaces a polished coating which consists in forming upon said surface a sticky drying oily'layer containing graphite, then applying dry graphite thereto, then polishing the 10 graphite, and finally baking said coating.

In testimony that I claim the foregoing as my own, I have hereto allixed my signature in the presence of tWo Witnesses.
